` wheel j, having a hemispherical body, rig- Be itknown that I, ALBERT EDWARD JONES, a subject of the King of Great Brltam, residmg 1n Fiume, Hungary, 2 Via `Volosca,

engineer, have invented certain new and use-` ful Improvements in and Relating to Mechanism for the Control of the Propellers of Y Automobile Torpedoes, of which the following is a complete specification.

`the control of the propellers of automobile This invention relates to mechanism for torpedoes by means of turbines. "The three conditions that mechanism of this type shouldfulil are as follows 1. It should comprise or itself constitute a `:reduction mechanism for reducing the speed ofrotation of the turbines to the desired extent suited to the propellers,

2. It should insure the rotation of the two propellers of the torpedoes in opposite directions, and

3. It should insure absolute mechanical dependence between the running of thetwo 1 propellers. `2.5`

Control mechanisms ofthe type in question fulfilling the conditions set forth above wwlhollyor in part, have already been constructed, but all of them present the defect of comprising an excessive number of elements so that they are too bulky and moreover they are imperfectly balanced;

The inventionhas for `itsobject control mechanism for the propellers of automobile4 torpedoes in which turbines satisfy the three conditions set forth by means of a mmnnum of elements with the minimum volume and moreover while elements.

In the accompanying'drawing:

Figure lis a horizontal longitudinal section of a portion of a torpedo showing the mechanism embodying the invention, in plan.

Fig. 2 is a longitudinal section in perpendicular to that of Fig. 1.

. The twoturbine wheels a and b rotate in opposite directions and they are arranged perfectly balancing these a plane i parallel to each other in two planes parallel to the longitudinal axis of the torpedo. The shafts c and rl of the turbines. carried respectively in appropriate bearings e and f. end respectively in the beyel pinions g and .These two pinions, which rotate in opposite directions, are in mesh on one sideof the shafts c and cl of the turbines with a gear Patented Feb. 12, 1918.

the propeller m of the torpedo. On the other side of the shafts c and d of the turbines these same bevel pinions also mesh with a gear wheel with hemispherical body 0 rigidly connected with the hollow shaft 79 of the other propeller Q. The two gears j and 0 are separated by an annular-gap t and form a cover for the turbine Wheels a and b. Fig. 2 shows the arrangement of the injection nozzles r of the turbines, the pipe s supplying the motor fluid to this nozzle passing through the annular space t.

The operation of the device is self-evident, and it will be noted that the three conditions enumerated above are fulfilled, that is to gear wheels j and o gives the desired gearing down, with these `four elements only, without.v any intermediate gear wheels or tram of gear wheels.

2. The two propellers g and m rotate in` opposite directions a and b; A p'` p l 3. Owing to the two gear wheels '7' and 0 as do the turbine wheels meshing with the two bevel pinions g and h `directly driven by the turbines. an invariable mechanical connection and absolute mechanical dependence exist between the rotation of 'thetwo propellers t] and m. Finally,

4. The two pinions g and 7L and the two gear wheels j and 0 act in the same manner at two diametrically opposite points, so that the efforts acting upon them or the forces that they transmit are perfectly balanced.

The invention therefore permits of obtaining with four elements only, that is to say the two pinions g and It and the two gear wheels 7' and o, a driving mechanism for the propellers b v the turbines which fuli'ils all the conditions required in the appliangles to l*said concentric shaftsn v2.V A constructionalforni of'autoinobileand gearing between the turbineshafts and I the" concentric shafts.
